「投稿」メソッドを使用してデータをサードパーティアプリケーションに送信するアプリケーションがあります。次に、投稿されたデータでJavaを実行しているサードパーティアプリケーションがHTMLページを提供します。プログラムで確認する可能性はありますかこのレンダリングされたページのソースコードでデータを見つけますか?
NameValueCollection data = new NameValueCollection();
data.Add("v1", "val1");
data.Add("v2", "val2");
HttpClass.RedirectAndPOST(this.Page, "http://DestUrl/Default.aspx", data);
public static void RedirectAndPOST(Page page, string destinationUrl,
NameValueCollection data)
{
//Prepare the Posting form
string strForm = PreparePOSTForm(destinationUrl, data);
//Add a literal control the specified page holding
//the Post Form, this is to submit the Posting form with the request.
page.Controls.Add(new LiteralControl(strForm));
}
public static void RedirectAndPOST(Page page, string destinationUrl,
NameValueCollection data)
{
//Prepare the Posting form
string strForm = PreparePOSTForm(destinationUrl, data);
//Add a literal control the specified page holding
//the Post Form, this is to submit the Posting form with the request.
page.Controls.Add(new LiteralControl(strForm));
}
private static String PreparePOSTForm(string url, NameValueCollection data)
{
//Set a name for the form
string formID = "PostForm";
//Build the form using the specified data to be posted.
StringBuilder strForm = new StringBuilder();
strForm.Append("<form id=\"" + formID + "\" name=\"" +
formID + "\" action=\"" + url +
"\" method=\"POST\">");
foreach (string key in data)
{
strForm.Append("<input type=\"hidden\" name=\"" + key +
"\" value=\"" + data[key] + "\">");
}
strForm.Append("</form>");
//Build the JavaScript which will do the Posting operation.
StringBuilder strScript = new StringBuilder();
strScript.Append("<script language="'javascript'">");
strScript.Append("var v" + formID + " = document." +

//(The order is important, Form then JavaScript)
